Display device and display method therefor

A display device, comprising a stretchable display panel and a control circuit, the stretchable display panel comprising a stretchable substrate and pixel islands arranged in an array in a form of rows and columns on the stretchable substrate, and the pixel islands comprise first pixels, wherein

• along a first direction, a respective one of second pixels is adjacently arranged at a same side of each of the first pixels so as to form one of a plurality of pixel groups, and each of the first pixels and the respective one of the second pixels in a same pixel group have a same luminous color;
• the first direction refers to a stretchable direction of the stretchable display panel;
• the second pixels are made of deformable materials;
• a stretch sensing module is also arranged on the stretchable substrate, and the stretch sensing module is in electric connection with the control circuit, the stretch sensing module is configured to sense a stretching degree of the stretchable substrate to determine whether each of the second pixels is stretched to a target area size;
• and
• the control circuit is configured to:
• control driving voltages of each of the first pixels and the respective one of the second pixels in the same pixel group to be input at a same timing sequence when the stretchable display panel is not stretched and is in a display state and the stretch sensing module determines that each of the second pixels is not stretched to the target area size, and
• control the driving voltages of each of the first pixels and the respective one of the second pixels in the same pixel group to be input in different timing sequences when the stretchable display panel is stretched in the first direction and is in the display state and the stretch sensing module determines that each of the second pixels is stretched to the target area size.
